“It’s overwhelming. Every emotion is hitting me all at once right now. I know that when I was on Station 6 [and realized that I had won the gold], it was all I could do to keep from crying.

Two world records were broken in the pool.
American swimmer Dana Vollmer took the gold in the women's 100-meter butterfly in a record 55.98 seconds.

And I think I just really worked on all the little pieces that create a time that is that fast, working on my start, working on my underwaters, that feel for the water and then having practiced it enough and worked on it enough that when I get up to race all I have to do is race," she said.
